Cl. 24205.1 3 ClaimsABSTRACT OF THE DISCLOSURE This invention relates to a'method ofaffixing slide fasteners to a garment opening, and more particularly theinvention relates to a structural combination wherein the slide fastenerand other elements of the garment, as well as fabric sheets, areintegrally joined by a thermal setting adhesive.

One of the most difficult sewing operations for the home dress maker isthe correct application of a slide fastener to the garment being sewn.Pattern manufacturers and slide fastener manufacturers suggest methodswhich require a variety of operations to obtain the application of aslide fastener to the material. In each instance, basting is required.Further the slide fastener must be opened and closed, and sewing firstone side and then the other with a zipper foot on the machine is alsorequired. After the sewing is completed, the basting is removed whichrequires additional time and effort. The completion of the above stepsin a uniform and neat manner requires considerable skill and in manyinstances the home dress maker is dissatisfied with the quality of theresults generally obtainable. Further it is difficult to do all of thesewing operations on the inside of the garment in such a manner that thestitching will not show on the finished side of the garment.

It is an object of this invention to provide a novel method for theapplication of the slide fastener to the garment with ease and dispatchand without the use of sewing operations.

It is a further object of this invention to provide a closurecombination for a garment or other construction utilizing a slidefastener wherein, the slide fastener is affixed to the marginal edges ofan opening by a thermal setting adhesive.

Another object of this invention is to provide a method for applying :3.slide fastener to the marginal edges of an opening in a fabric panelwherein the fastener tape is joined to the fabric by placing a thermalplastic adhesive or resin there between and applying a hot iron tosoften the adhesive which upon cooling provides a permanent bond betweenthe slide fastener tape and the fabric panel.

Other objects and advantages more or less ancillary to the foregoing andthe manner in which all the various objects are realized, will appear inthe following description, which considered in connection with theaccompanying drawings, set forth the preferred embodiments of theinvention.

In the drawings:

FIG. 1 shows a cross-sectional view of the preferred embodiment of myinvention wherein, the panel opening is closed with the edges in side byside relationship;

FIG. 2 shows the panel with the rebent edges prepared for theapplication of the slide fastener;

Patented Feb. 9, 1971 FIG. 3 shows the super imposed panels with thebasting spaced from the edges;

FIG. 4 shows the basted opening of FIG. 3 prepared for the applicationof the slide fastener as shown in FIG. 1; and

FIG. 5 shows the cross-sectional view of slide fastener applied to aplacket type opening.

Referring to the drawings and particularly to FIG. 1, a section 10 of agarment is shown therein as seen in a sectional view of the completedclosure. In FIG. 2, section 10 of the garment or panel having an openingtherein to be closed is shown with the marginal edge 12 rebent andhaving a width of approximately one-fourth inch. The edge 12 ispreferably pressed to form a smooth and uniform margin for the opening.

A slide fastener 14 having tapes 16 and 18 affixed thereto, ispositioned over the opening line with the front of the fastener towardsthe edges 12. A strip 20 of thermoplastic material having adhesivecharacteristics is positioned along the length of the slide fastenerstapes 16 and 18. One strip 20 is positioned to contact the section 10and the other strip 20 of the thermo-plastic adhesive is positioned tocontact the edge 12. It is contemplated that the strips 20 ofthermoplastic material would be applied to the tapes 16 and 18 at thetime of the manufacture of the slide fastener.

When the tapes 16 and 18 are in over-lying relationship with the edge 12and section 10 a hot iron is applied to the tapes and under theinfluence of the heat and pressure from the iron the strips 20 of thethermo-plastic adhesive soften and migrate into the tapes 16 and 18 aswell as the sections 10 of the garment and the marginal edge 12. Uponremoval of the iron the adhesive cools and provides a permanent bondbetween the materials of the garment and the tapes 16 and 18 affixed tothe slide fastener 14.

In preparing the openings to be closed by the slide fastener of saidopening the length should be the same as the length of the teeth portionof the slide fastener 14 with an additional one-half inch. The openingmay be closed with machine basting on the seam line as shown in FIG. 3with the seam allowance trimmed to leave no more than one-fourth inchafter which the basted opening may be pressed open as shown in FIG. 4.The slide fastener teeth are placed face down and in line with thestiched part of the seam as shown in FIG. 1, with the thermoplasticadhesive 20 in place and the slide fastener in super imposed as shown inFIG. 1. The application of the hot iron to the tape on one side formsthe attachment thereto, and then when the iron is touched to the otherside the attachment is complete.

In FIG. 5, a placket closure is illustrated, and in this instance, onlyone side of the seam allowance is trimmed to one-fourth inch. The chainof the slide fastener 14 is then placed against the ironed fold of thematerial 10 and in contact with edge 12 and the iron is applied theretoto soften the thermo-plastic adhesive 20 and afiix that portion of theslide fastener 16 permanently in place. The flap 22 of the seam fabricand main fabric 10 is then positioned over the slide fastener 14 and theopposed portion of the section 10. The tape 18 of the slide fastener isthen brought into contact with rebent edge 12 and the section 10 withthe thermo-plastic adhesive 20 there between. Application of the hotiron to the tape 18 results in the tape 18 being permanently afiixed tothe edge 12 and the section 10 with the flap 22 in its properrelationship to the placket closure.

The description herein is directed to garment closures but it isunderstood that the description and claims may apply equally to otheruses and construction wherein slide fasteners are used to close or jointwo fabric panels for ready separation.

Having thus described this invention in such full, clear, and conciseand exact terms as to enable any person skilled in the art to which itpertains to make and use same, and having set forth the best modecontemplated of carrying out this invention, I state that the subjtctwhich I regard as being my invention is particularly pointed out anddistinctly claimed in what is claimed, it being understood thatequivalents or modifications of, substitutes for, part of the abovespecially described embodiment of the invention may be made withoutdeparting from the scope of the invention as set forth in what isclaimed,

What is claimed is:

1. The method of applying a slide fastener to a garment for closing anopening, said slide fastener having tapes which carry thermal plasticand thermal setting adhesive comprising the steps of placing the sidesof an opening in the garment in juxtaposition, folding the sides of theopening to form a rebent portion forming a One-fourth inch wide marginaledge and pressing same, stitching the edges of the opening together,placing the slide fastener with the teeth face down and in line with theopening and covering said marginal edge, applying a hot iron to theslide fastener tape and applying pressure thereto, and holding thematerial of the garment and the slide fastener tape in position untilthe same has cooled.

2. The method of applying a slide fastener to a garment as defined inclaim 1 wherein the fastener tape overlaps the marginal edge and isjoined to the material beyond said marginal edge when the heat isapplied thereto.

3. In a garment construction having a slide-fastener for closing anopening therein comprising a slide fastener having a pair of tapesafiixed thereto, edge sections of said garment having a main section anda rebent marginal edge overlapping said main section, each of said tapesoverlapping said edge sections of said garment opening, a thermo plasticadhesive between the tape and the said rebent marginal edge therebysecuring same together and between the tape and said main sectionthereby securing them together whereby said slide fastener ispermanently affixed to said edge sections of the garment when heat andpressure are applied with an iron, said adhesive being the sole means ofsecuring said tape to the edge sections.
